If your not prepared to lose all the personal data ( music, pictures, documents, etc.) you must make backups. Over 40% of PC users lose their data every year. Something as simple as a power failure or your hard drive failure, can cause you to lose important data.
It is also very common, that malware can so affect WINDOWS SYSTEM files, that there is a real chance of losing access to your files after removing the Malware! This makes backing up especially important before attempting repairs.
Some of your options include: Saving files to Thumb drive (USB), CD or DVD, Creating incremental backups on External Hard drive, or NAS (network attached storage), or using an online backup service. NAS and Online Backup both accommodate multiple computers.
1 - You can use it where ever there is access to the internet.
2 - Your backups are stored remotely, away from originals, where they are not both likely to be lost to flooding, power outage, theft, or fire.
An essential step to fixing a slow computer, is backing it up.
